WATER-CLOSET SEAT ANT) COVER III INGE.

To all ir hom it may concern:

Be it known that I, BERT O. TILDEN, 21 tion of the seat, cover and hinges.

citizen of the United States, residin at Trenton, in the county of Mercer and tate of New Jersey, have invented certain new :a nd useful Improvements in Water-Closet Seat and Cover Hinges, of which the following is a specification.

his invention relates to unprovements in water-closet seat and cover hinges, and has for its object to provide a novel and simple hinge mechanism adapted for pivotally connecting closet seats and covers to the usual closet bowls, whereby a saving in the amount of metal comprising the hinges is effected and whereby the usual metal "plates or leaves, which are invariably mounted on the exposed tops or bottom sides v of th seats and covers and fastened thereto b screws, are eliminated. A further objec is to provide a hinge structure in whici the means for securlngthe hinge pirt's to the seat and cover are concealed d the top and bottom surfaces of the seat and cover are left free and clear, which 'rnders. the said part more. sanitarymore readily *clcaned and kept clean. 'A further 'object is provide a hinge of the class I/which' is sd\ eonstructed and appliedthat when the seat and cover are lifted or swung upwardly away from the bowl they ,IOWS, and as illustrated in the accompanydrawing, in which' igure 1 is a top plan vlew of awaterclosct outfit, having my improvement applied thereto.

Fi .2 is a side-elevation of-the same; showing by full and dotted lines the closed and open position of the seat and cover.

Fig. 3 is an enlarged broken side view; showing the hinge members and the seat and cover indifferent positions.

Figs. 6 and 7 are respectively an edge and hinge post which allows a greater roughing measurement than the straight posts in Figs. 2,3,4,and5. I

In the drawing, represents a portion of the closet bowl, and 3 a low-down flush tank of conventional form, connccted'by a flush pipe 3.

-5 represents a closet seat which may follow any of the usual constructions, but preferably has a reduced portion 6, at its rear end adjacent the tank 3. cover for the seat of somewhat smaller area, and which has a similar reduced rear end 8,

preferably corresponding in breadth to'the projection 6 of the seat. The op rsitc edges -oi. the projections (5 and8 are preferably parallel, as shown in Figs. 1,4, and 5.

My improved hinge or hinges are disposed 'at the opposite rear corners of the closet seat and cover, and the exposed parts of the hinges are preferably entirely disposed at or on the lateral edges of tj ie projections 6 and 8, and consist of the to 1 represents similar hii'ige posts having balllike headslO, intermcdiateflanges 11 which rest upon the top surface of the closet bowl 2, and screw-threaded stems 12 which pass through suitable perforations 12, in the bowl. The posts 9 are preferably held in place by wing-nuts 13, andhetween the said nuts and the under s'urfaee,of"rthe bowlis .;usually disposed rubber washers .13; The

' the seat and cover. Each member or bracket posts 9 are preferably straight and are 7 represen the' owing parts: 9'

spaced apart sufliciently to loosely receive the reduced rear-end G'of the seat- 5, as best seenin Figs. 4 and 5. The heads 10 of the posts are provided with horizontal sockets- -14, which face the said ortion 6.- 15 repreare mounted so as to overlap the opposite lateral edges of the projections 6 and 8 of 15 has afperforation 15 near one end concentric to the socket 14 of the co'rresE ing post'9. Each bracket .15 is prdvid j V its inner surface with lugs or 1 sents similar hinge mem ers or plates, which j brackets rigidly in the proper position rela- .rodnced portion 6 ot' the seat.

'soat ti\ely to thevseat and cover, as well as to render tlt'e-m movable with the seat." 1% rep resentg pintles which pivotally connect the Sfto the posts 1 llach pintle 15 compris ska cylindrical head 1H which engages the socket ll of the adjacent post. and a threaded portion 18 which passes through the perforations 10 and is screwed.intothe The pintles 18 being rigid in the seat they turn in the sockets H whenever the scat'is raised and lowered. \Vhen the bolts 18 are screwed into the seat the heads 18 being la ru'erthan the perforations 1t}, draw and rigidly hold thelplates .15 tightly against the opposite' edges of the seat. The pivot means for the cover consists of similar plain pins 19', which are preferably driven tightly into the opposite edges of the-projection 8 of the cover. their outer free ends being inserted in sockets :20 formed near the opposite ends of the members 15 (see Fig. 5). By this construction and arrangen'ient. the cover may be raised and lowered independently of the scat, by the pins 1!. turning in the sockets 20. After the members 15 are applied to the lateral etlges'ot' the eat and cover. and the bolts 18' are screwed in tight, as shown and .described, the-scat and cover are securely connected to each otherand may 'be rotated-as one parton the pivot H l To apply the seat and cover to the closetbowl. the posts 9 are first slipped over the heads 18 of the bolts 1.5. then the threaded stems 12 of said posts are inserted downwardly througlrthe perforations 12 in the closet bowl. and the wing-nuts applied. as

" shown.

The. sockets '1-1 and the pintlc heads 18 are preferably disposed substantially in the line of the longitudinal axisof the seat 5, as indicated by-=the broken line in Figs. .4 and 5. 'hen the seat 5 is raised to the yertical position shown in Figs. 2 and the said axis A ot' the seal is directly in line" with the: ve'rti al (see Fig. 3). I lleretolorc, plumbers when luakingtheir -ro u;.rhin'g 'in" measurements. frequently axis ol' the po ts f f madethe mistake of locatingthe pipes to to the walls of the toilets against which the which the closet bowls are attached. too close whereby in case a mistake in such measurements is made. a closet bowl and tank may still be installed according to the measurements without relocating the floor pipes, and. .f

a cover and seat equipped with my improved hinge mechanism will stand upright without a ttention, or the aid ot any extra parts. By

referring to Figs. 2 and 3, it will be seen' that both the seat and co er may be raised and left in the trueyertical position and they will not fall accidentally. This result is attained by the peculiar shape of the hinge members 15 and the positioning of the same and the pintles 1S-19 relatively to the seat and cover. as well as to the posts 9, as shown in the enlarged view in Fig. When the seat and cover are disposed in upright covers were both raised position. the upper or free ends ot the members .15 wluch support the cover 7. are tilted bzu'kwardly considerably beyond the main or hxed pivot center A, which is the center of the sockets 1 t and the' heads 18 of the pintles 18, and when the seat and cover are placed in thisupright position, the weight of the coyer shifted an inch or more rearwardly ot the said center ;\",Which is enou h to positively overcome the tendency of t 0 seat. which is larger and heavier than the covtl. to accidentally gravitate to'tho bowl. This feature is an important one; not only because it eliminates the extra counter weight parts referred to. and the extra expense-and labor of applying such parts but by its provision 1 am enabled to [H'Utlllt'Q closet seat and cover hinges. which permit close "roughing in" as explained. and which are lightand cheap. yet strong and durable. B;\' the use. of my improved hinge mechanism. a closet can be kept clean and sanitary and will stand long: use. because there are no complicated or obstructing parts to hinder cleaning. and there are no screws or other attaching parts employ ed to split or otherwise mar or injure the material of the seator cover. Owin to the damp conditions of toilets, the

metal parts employed in and about water amount of said metals. which tends to keep down the cost o'l" such fittings.

In Fig. 8 I have shown a closet seat 5 which is pivoted by a pintlo 14 in the head of an olf-set post 9', and a cover supporting plate 15 the same as in the preceding figures of 'the drawing. Ihis view is important in that it shows the adaptability of my improved hinge mechanism to the old oil-set or curved posts, wherein more liberal roughing measurements are obtainable.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is-- 1. A closet seat and cover hinge comprising a post having a socket, a threaded pintle having a head pivoting in said socket, a hinge member adapted to overla a closet seat and cover having a perforation to receive said pintle and having socket, and a pin rigid in the cover and pivoting in the socket of said member.
